Comments and Reviews
Very nice software to explore the universe. Runs on my older computer.
The best simulator out there I've seen, though I have not seen the one it led to, who's name I forget. It's of real use.
I love this software very much! However it seems the website/forum is not available. I think the developers stopped the software. The latest release was also from 2011. Too bad :(
